Cinnamon (肉桂 ròu guì) has in vitro insulin potentiating activity, and proanthocyanidins from cinnamon prevent in vitro formation of advanced glycation end products. Some human studies were equivocal, but several have shown beneficial effects of cinnamon supplementation on circulating glucose, lipids, and/or insulin. This placebo-controlled double-blind trial tested the effects of a dried water extract of cinnamon (Cinnamomum cassia) on circulating glucose, lipids, insulin, and insulin resistance. Men and women from Beijing and Dalian, China, were invited to participate if they had fasting serum glucose >6.1 mmol/L or 2-h glucose >7.8 mmol/L. Participants, (173 were enrolled and 137 completed the study) were randomly assigned to receive either a spray-dried, water extract of cinnamon (CinSulin®), 250 mg/capsule, or a placebo, twice a day for two months. Mean ± SEM age of participants was 61.3 ± 0.8 years, BMI was 25.3 ± 0.3 and M/F ratio was 65/72. After 2 mo, fasting glucose decreased (p < 0.001) in the cinnamon extract-supplemented group (8.85 ± 0.36 to 8.19 ± 0.29 mmol/L) compared with the placebo group (8.57 ± 0.32 to 8.44 ± 0.34 mmol/L, p = 0.45). Glucose 2 h after a 75 g carbohydrate load, fasting insulin, and HOMA-IR also decreased with cinnamon extract compared with placebo. Total and LDL-cholesterol decreased with cinnamon extract and HDL-cholesterol decreased in both the cinnamon-extract and placebo groups. In conclusion, supplementation with 500 mg of water-extract of cinnamon for two months reduced fasting insulin, glucose, total cholesterol, and LDL cholesterol and enhanced insulin sensitivity of subjects with elevated blood glucose.

We aimed to evaluate the contribution of the G-protein β3 subunit C825T (GNB3-C825T) polymorphism to essential hypertension (EH) in Han Chinese population by performing meta-analysis. A meta-analysis was performed in 12 case-control genetic association studies including 3,020 hypertension patients and 2,790 controls from MEDLINE (PubMed) and the China National Knowledge Infrastructure platforms. The STATA 10.0 software was used in analysis. Overall, there was no significant association between the GNB3-C825T polymorphism and EH in neither additive [TT vs. CC: OR (95 % CI) = 1.11 (0.74-1.69), P = 0.61; TC vs. CC: OR (95 % CI) = 1.08 (0.89-1.31), P = 0.42], nor dominant [TT + TC vs. CC: OR (95 % CI) = 1.11 (0.86-1.42), P = 0.43] and nor recessive [TT vs. TC + CC: OR (95 % CI) = 1.04 (0.75-1.44), P = 0.81] genetic models. Although further subgroup analysis found statistically significant results [T vs. C: OR (95 % CI) = 1.50 (1.05-2.15), P = 0.03] in the southern population, but after exclusion one particular study, the significant association was disappeared. No significant result was found in the northern Han Chinese population. There was no significant association identified between GNB3-C825T polymorphism and EH in Han Chinese population. Further larger sample and well-designed studies are needed to assess the genetic association particularly in the southern Han Chinese population.

The article records details of the treatment process and effect of an elderly patient with senile vaginitis, where needling, a method of Chinese Traditional Medicine (TCM) method, was applied mainly, combined with oral administration of western medicine. It then analyses this disease from prospective of TCM. In the end, it concludes that no matter traditional needling method or traditional needling method combined with moxibustion, it has achieved a satisfied treatment effect while applying needling on chosen acupuncture points, so it is worthy being further popularized.
